function varargout = myaudioplayer(varargin)
% MY_MUSIC_ANALYSIS_SOFTWARE M-file for my_music_analysis_software.fig
% MY_MUSIC_ANALYSIS_SOFTWARE, by itself, creates a new MY_MUSIC_ANALYSIS_SOFTWARE or raises the existing
% singleton*.
%
% H = MY_MUSIC_ANALYSIS_SOFTWARE returns the handle to a new MY_MUSIC_ANALYSIS_SOFTWARE or the handle to
% the existing singleton*.
%
% MY_MUSIC_ANALYSIS_SOFTWARE('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MY_MUSIC_ANALYSIS_SOFTWARE.M with the given input arguments.
%
% MY_MUSIC_ANALYSIS_SOFTWARE('Property'.'Value',...). creates anew MY_MUSIC_ANALYSIS_SOFTWARE or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before myaudioplayer_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to myaudioplayer_OpeningFcn via varargin.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)".
